We are excited to announce that Amazon Route 53 health checks now support endpoints with Internet Protocol Version 6 (IPv6) addresses. Last month, Amazon Route 53 began rolling out support for DNS queries over IPv6. With today’s release, customers can now use Amazon Route 53 health checks to monitor resources with IPv6 addresses.

Internet Protocol Version 6 (IPv6) is a new version of the Internet Protocol that uses longer IP addresses (for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334) than the previous version of the protocol (for example, 192.0.2.44). With IPv6 support for health checks, you can configure DNS failover and health monitoring of endpoints that have IPv6 addresses, which allows you to monitor IPv6 connectivity to your applications.
